Abstract: 500,900. Cigarette &c. igniters. RINGER, F. Dec. 1, 1937, Nos. 33215 and 33216. Convention dates, Dec. 1, 1936 and Nov. 22, 1937. [Class 75 (iii)] In an igniter in which a solid fuel containing fibres is ignited by a frictional sparking device, means are provided for releasing the fuel in its carrier and resiliently pressing it against a device for roughing-up the surface thereof, for imparting relative movement between the fuel and the roughing-up device and for reclamping the fuel in its carrier prior to ignition. In one form, in which a friction-wheel 6, Fig. 1, is actuated by the opening of a hinged cover 2, a spring-pressed bar 4 is depressed to move a slidable member 15 for swinging a lever 12, carrying a roughing- up device 13, against the action of a spring 18, and a ring 10, released by a stop on the cover 2 or member 15, is forced upwardly by a spring 21 to clamp the spring-pressed solid fuel 8 in the carrier 9, which is slit at the upper end and conical on the outside. In a second form, the device 13, Fig. 2, is carried by a spring-pressed arm 22, pivoted to the cover, and the clamping ring 10 is connected to a lever 29 having an arm 27 for engaging an arm 25 in the cover. In a third form, the device 13, Fig. 3, is carried by a spring-pressed arm 22<1>, adapted to control the lever 33 of the ring 10 and provided with a roller 30 which slides on a guide 31. In a fourth form, the fuel carrier 9, Fig. 4, is rotated in contact with a fixed device 13 in the cover 2 by means of a button 34 provided with a pin 41 for actuating a spring-pressed locking lever 37 for the cover, the ring 10 being released by the opening of the cover. In a modification, the carrier 9 carries a locking projection and is rotated by means of an arm thereon projecting through a slot in the casing. In a fifth form, the fuel 8, Fig. 7, is ignited by rubbing a flint or lug 45 on the detachable carrier along an external friction surface 42. The carrier comprises a spring-pressed sleeve 9 and a slidable clamping sleeve 43 secured to a handle 44, the sleeve 9 being provided with a pin 46, extending through a slot in the handle. When the pin 46 is engaged in a bayonet slot 47 in the casing, the sleeve 43 releases the sleeve 9 and the fuel is roughed-up by the spring-pressed device 13. The carrier is detachably held in the casing by means of balls 48, connected by springs to the casing and adapted to engage recesses in the sleeve 43. In a sixth form, an operating lever 57, Fig. 9, is connected by a pin 59 and a slot 58 with a slide 60 attached to a rack 62 engaging a pinion 63 to rotate the carrier 9 in contact with a fixed roughing-up device 13 in the hinged cover 2. A pivoted spring-controlled catch 54 on the carrier 9 is released from a stop on the casing so that teeth 55, thereon project into the interior of the carrier to hold the fuel. A helical spring 67 engaging a notch in the lever 57 is also stressed until a projection 64 on the lever operates a pivoted catch 65 to release the cover 2. On returning the lever by pressing on its lower arm, the parts are returned to the normal position, the cover 2 being closed by a projection 68 on the lever. A slidable stop pin 73 is provided in the casing for operating the catch 54 when the igniter is open to allow for changing the fuel. As shown in Fig. 12, the fuel 8 may be fed by a spring 76 until a projection 78 on a plate 77 engages a ramp 86 and pushes a pawl 84 outwardly to release a spring-pressed sleeve 80 for feeding the last part of the fuel. In a seventh form, the casing 89, Fig. 15, is pivoted at 88 in a frame 87 for attachment to a wall. When the casing is swung forwardly into the position shown, the device 13 is rotated by the pinion 93 moving along the fixed rack 94. Guides 95 for the casing 89 act as stops for pins 96, which slide in slots in the carrier 9 and are connected to a spring-pressed catch 98 for holding the fuel, so that the catch 98 engages the .fuel just before the pinion leaves the rack and the cover 91 is swung up by a spring 92 for operating the friction-wheel 6 to ignite the fuel. The carrier 9 is removable for changing the fuel or for use after ignition. The fuel may be of the type described in Specification 497,619, [Group XII].
